The FT61F0A5-TRB is a Other Processors and Microcontrollers (MCUs) TSSOP-20 RoHS manufactured by Fremont Micro Devices. It is a low-power 8-bit microcontroller with an enhanced 8051 core, 16K bytes of FLASH program memory and 384 bytes of RAM, 2 programmable timer/counter, one UART, 10-channel 10-bit A/D converter, software I2C interface, and eight I/O ports. It is RoHS compliant and features an integrated on-chip Voltage Regulator, Clock Generator and Self-Timer capabilities, integration of a power saving Sleep Mode, Brown-out detection, and programmable internal clock source. This MCU also includes support for two communication components (UART, I2C) and four basic peripherals (Timers, A/D Converter, Reset Circuit). The TSSOP-20 version of the FT61F0A5-TRB allows the device to be packaged in a compact size, making it ideal for applications where board space is at a premium.
